Add in an sti air filter and you're running a very decent stage one and will amost certainly make more power than PPP. You'd also have an ecutek licence meaning future mapping is much cheaper, this is more of an issue if you see yourself making future modifications. Do you know how far you'd like to go?
As has already been stated the PPP is a one size fits all map and therefore is a compromises, a map from Andy will bespoke and get the best from the car.
